Multijet Rotative Valves
Nencini designs and produces multijet rotative valves.
The simplicity of the design allows this valve to work under heavy flow condition for a long time. It is composed by one multi-hole plate assembled between two propeller-shaped plates, one fixed and the other rotating on the common axis. The valve control the flow operating in the full range between two end positions:
■ open when the blades of the two propellers are perfectly aligned
■ closed when the blades of the movable propeller overlap the empty room of the fixed propeller.
The multi-hole plate provides a downstream flow in evenly distributed jets.
■ water distribution systems
■ supply of reclaimed water for agricultural use and recharge of basins
■ headwork of water treatment plants
■ flow relief for pump, turbine by-pass and other hydroelectric utility applications
■ water intake at the bottom of dams and discharge control.
